fuel injector cleaner

ultimately had to replace all 4 injectors as they failed resistance testing. All four were clean as a whistle! All four holes and surrounding area were clean and carbon free!

So far it seems to work as for performance. Don't know if it is effective on cleaning the valves or injectors.

Best fuel additive period

Excellent product at 8-10 dollars off the store price at OReillys or Advance Auto. Only use once every 12000 miles. Makes the engine run hot; it can shut off the "check engine light" because it works so well.
